(What's So Funny 'Bout) Peace, Love & Understanding lyrics

As I walk through
This wicked world
Searchin' for light in the darkness of insanity.
I ask myself
Is all hope lost?
Is there only pain and hatred, and misery?
And each time I feel like this inside,
There's one thing I wanna know:
What's so funny 'bout peace love
